Hollyhocks (Alcea rosea) are towering, majestic flowers known for their dramatic height, colorful blooms, and old-fashioned charm. These biennial or short-lived perennial plants can grow up to 8 feet tall, making them ideal for cottage gardens, borders, and backdrops. Hollyhocks are pollinator-friendly, attracting bees, butterflies, and hummingbirds. They thrive in full sun and well-drained soil, and though they are relatively easy to grow, they are susceptible to rust disease. Proper care and maintenance can ensure that these flowers bloom from mid-summer to early fall, creating a beautiful and nostalgic display in the garden. Hollyhocks add a stunning vertical element to any landscape. While growing them from seed requires patience, their stunning blooms and ability to attract pollinators make them worth the effort.

How to Plant Hollyhock from Seed

When to Plant Seeds

  • Outdoors: Sow seeds in late summer to early fall for blooms the following year.
  • Indoors: Start seeds 6-8 weeks before the last frost for transplanting.

Seed Preparation

  • Hollyhock seeds do not require stratification.
  • Soaking seeds in warm water for a few hours before planting can speed up germination.

Sowing Seeds Outdoors

  1. Choose a well-drained, sunny location.
  2. Loosen soil and mix in organic matter.
  3. Scatter seeds on the surface and lightly cover with 1/4 inch of soil.
  4. Water gently and keep the area moist until germination (about 10-14 days).
  5. Thin seedlings to 18-24 inches apart for proper growth.

Starting Seeds Indoors

  1. Use peat pots or seed trays with a well-draining seed mix.
  2. Sow seeds 1/4 inch deep, keeping the soil moist but not wet.
  3. Maintain a temperature of 65-75°F for germination.
  4. Once seedlings develop two sets of true leaves, harden them off and transplant outdoors.

Pro Tip

They’re biennials, so for continuous blooms, plant seeds two years in a row. Stake tall varieties to keep them from toppling over, and let some flowers go to seed for natural reseeding next season.

Bonus: They attract butterflies, bees, and hummingbirds!

Getting to know your Hollyhock

Hollyhock is a biennial or short-lived perennial known for its towering flower spikes that can reach 6-8 feet tall. It thrives in full sun and well-drained soil, producing large, colorful, funnel-shaped flowers in pink, red, yellow, purple, and white. Hollyhocks attract pollinators like butterflies and hummingbirds and are commonly planted along fences or cottage gardens. They require support due to their height and benefit from staking. These plants are susceptible to rust fungus, so proper air circulation and well-spaced planting help prevent disease.
